Can some one explain how does pericardial diseases like cardiac`temponade or constrictive pericarditis contribute as pre renal causes of renal failure?

Also how does coarctation of aorta cause renal failure?


I found out that Coarctation of aorta can cause renal failuire due to either poor collateral supply or if ductus srteriosus is closing,then due to reduced blood supply to lower part of the body like intestines and kidneys.


Cardiac tamponade and constricitve pericarditis are both associated with decreased cardiac output.This leads to diminished renal blood flow and a decline in renal function.
